Specification of Letters Patent.

Patented Aug. 1?, 1915.

To all whom it may concern:

Be i known that we, JULIUS Pnnn'rz and BAnNnY COHEN, citizens of. the United States, and residents of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Sad-Iron, of which the following is a full, clear, and exact description.

Our invention relates to sad irons heated by the combustion of gas within the iron.

An object of the invention is to provide a simple, strong, efficient, and inexpensive iron in which the flame is generated by a burner located within the iron, said iron having an undulating surface on which the gas flames are caused to play, so that the maximum surface is exposed to the flames and, consequently, very little he. t-generated by the burner is wasted.

A further object of the invention is to provide a sad iron in which the products of combustion coming from the burner are deflected from the operators hand by providing baffles on the cover for the iron.

\Vith the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention conslsts 1n the novel construction, combmation and arrangement of parts as herein fully described,-illustrated and claimed.

In the accompanying drawings forming part of the application, similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of our iron,

7 partly in section, on line 1-1, Fig. 2; Fig.

2 is a horizontal section on line 22, Fig. 1; and Fig. 3 1s a transverse section on line as, Fig. 1.

Referring to the drawings, the main body 4: of the iron is in the shape of a hollow casing which has at the bottom thereof a longitudinal hollow projection 5 lying in the longitudinal axis of the body and open through its entire length within the iron, as shown at 6. The projection is also open at the rear end of the iron and wherethrough air enters into the hollow projection. A longitudinal ridge 7 is provided withinthe hollow projection which partly enters into the opening 6 whereby two independent air inlets are formed within the hollow'projection to each side of the longitudinal axis of the casing. An integral lug 8 is provided on the longitudinal projection substantially in the middle of the casing.

Engaging the lug 8 is a gas burner 9,

the flame-generating outlets 10 of which are directed toward the bottom of the casing. The gas burner 9 is maintainedrni proper position within the casing by a set screw 11 provided in the lug 8. By forming the lug 8 in the middle of the iron access to the clamping means of the burner is rendered easier; also, the burner 9 can freely expand toward both sides of the lug 8.

. To increase the surface on which the gas flames play, thebottom 12 of the casing is provided with ridges 13 extending transversely of the casing between the side walls thereof and the walls of the air passage 5. These ridges render the bottom of the easing undulated and, consequently, expose a larger surface to the flames than an ordinary flat bottom would expose, consequently increasing the efliciency of the iron. By making the ridges 13 an integral part of the bottom, no heat is lost through the imperfect contact that is generally caused by placing a corrugated sheet on the bottom of the iron, which is necessarily insulated from the bottom by an air cushion. To facilitate the combustion, openings 1 1 are provided in the rear wall of the casing. The products of combustion are directed by the walls of the casing toward the top thereof. No openings or escapes are provided within the casing at the bottom.

To prevent the heat escaping from the top of the casing from flowing toward the hand of the operator, a cover 15, which is hinged to the casing at the rear thereof, has depending side flanges 16 overhanging the sides of the casing and spaced from the top of the casing to leave an ample opening all along the sides. Adjacent the front, the side flanges 16 are preferably out off to enlarge the outlet for the products of combustion. A clamping member 17 is provided on the casing 4 adapted to engage the cover 15 to secure the cover to the casing",- as is common in this class of irons.

While we have described the principle of operation, together with the device which we now consider to be the best embodiment thereof, we desire to have it understood that the device shown is merely illustrative and that such changes may be made as are within the scope of the appended claims.

We claim:

1. In a sad iron, a hollow casing having an internally corrugated bottom and longitudinal air passages open at the rear of the casing and also through the entire length within the casing, the longitudinal air passages having their openings in the casing above the corrugations of the bottom, a burner located above said passages and adapted to direct the flames into the corrugations of the bottom, and a cover for said casing hinged thereto.

2. In a sad iron, a hollow casing having a hollow longitudinal projection open at the rear end of the casing and through the entire length within the casing, a lug on said casing substantially in the middle thereof, a burner clamped within said lug and located over said hollow projection, said burner having fiame generating openings so located that the flames can play to each side of said hollow projection, a longitudinal ridge within the hollow projection extending through the entire length thereof and forming two distinct air passages for the casing in said hollow projection, said casing having transverse ridges extending from the side walls to the walls of the hollow projection and transforming said bottom into a corrugated one, the flames from said burner being adapted to play within the corrugations of the bottom, and a cover hinged to the rear of said casing and having a handle for manipulating the iron.

3. In a sad iron, a hollow casing having an internally corrugated surface and a hollow, longitudinal projection open at the rear of the casing and also through its entire'length within the casing and forming an air supply means for said casing, a

burner within the casing over the longitudinal opening of said hollow projection for directing the flames on to the corrugations, and a'cover for said casing.

4:. In a sad iron, a hollow casing having a longitudinal, hollow projection open at the rear end of the casing and longitudinally through the entire length of the casing, a ridge within the hollow projection extending through the entire length thereof and into the longitudinal opening, whereby two independent air passages are formed in said hollow projection for said casing,-

a burner within the casing positioned above the hollow projection, and a cover for said casing: r r

5. In a sad iron, a hollow casing'having a longitudinal, hollow projection open at the rear end of the casing and having a longitudinal opening extending through its entire length withinthe casing, a lug on said hollow projection substantially in themiddle ofthe easing, a burner clamped within said lug and located over said longitudinal.

opening of the projection, a ridge within said hollow pro ect on extending substantially through its entire length and entering into the longitudinal opening of said hollow proection, whereby two lndependent air passages are formed withln sa d hollow pro jection for the casing, and a cover'for said HARRY M.
